Timeless Manornotes from Sarah's porch
the folder I keep

What lasts, what silvers, what fades

I started keeping these notes after I threw away my second patio set. Nothing here is a recommendation — it's what each material actually does in year three, including the parts nobody photographs.

The woods

Teak

Silvers to grey in ~12 months · oiling optional

Left alone, teak turns a soft silver-grey within a year — evenly, if it gets even light. This is oxidation of the surface only; the wood beneath is unchanged and its natural oils keep it from rotting. Oil it if you want the honey colour back, and understand you are then committed to oiling it every spring. Grade A (heartwood, tight grain, no knots) silvers evenly; lower grades go blotchy. Nothing about the greying shortens its life.

Upkeep: One afternoon a year, at most. None, if you like grey.

Acacia

Needs oil yearly · will check if it doesn't get it

Acacia arrives looking a great deal like teak and costs a great deal less, which is exactly why it appears in so many sets. It has far less natural oil. Under sun and rain it dries, and dry acacia checks — fine cracks along the grain, usually inside two seasons. Oiled every spring and moved under cover for winter, it will give you many good years. Left out and forgotten, it will not.

Upkeep: An hour every spring, and a place to put it in January.

The metals

Powder-coated steel

Fails at the welds first, not the flat faces

The coating is tough and the flat panels usually outlast everyone's expectations. Rust starts where the coating is thinnest — the welds, the cut ends of tubing, the scratch where the chair met the door frame. Touch those up the week you notice them and the frame lasts a decade. Ignore them for a winter and the rust travels underneath the coating, where you cannot reach it.

Upkeep: Ten minutes with touch-up paint, once a year, at the joints.

Cast aluminium

Will not rust · will chalk in strong sun

Aluminium cannot rust, which removes the failure that ends most metal furniture. What it does instead is chalk: the finish oxidises to a fine white powder that comes off on your hand and dulls the colour. A wash and a coat of automotive wax restores it. It is also light — genuinely light — which is a virtue on a deck and a liability in a gale.

Upkeep: A wash and a wax each spring. Something to tie it down.

The weaves

Rope weave

Stiffens after a wet winter · relaxes again in warmth

The olefin and polyester ropes used on good outdoor seating are UV-stable and will not rot. They do stiffen when cold and damp, and a rope chair left out through a wet winter feels like a different chair in March — it softens again as the weather turns. Real deterioration shows as fuzzing at the points where the rope crosses the frame. That is abrasion, not weather, and it is the thing to inspect.

Upkeep: Nothing, most years. Look at the crossing points each spring.

All-weather wicker

The resin lasts · the frame inside decides its life

The woven resin (HDPE, if it is any good) survives sun and rain almost indefinitely and cleans with soapy water. Poor wicker fails in one of two ways: the strands go brittle because they are PVC rather than HDPE, or the aluminium frame beneath is thin enough to bend and the weave then splits at the corners. You are buying the frame. The weave is what you can see.

Upkeep: Soapy water twice a year. Check the corners.

The textiles

Solution-dyed acrylic

Fades honestly and slowly · the seams go first

Colour in solution-dyed acrylic goes all the way through the fibre rather than sitting on it, so it fades slowly and evenly instead of going patchy. Expect a gentle softening of tone over five or six seasons, which most people never notice. What ends a cushion is the stitching and the zip, both of which sit on the surface and take the full sun. Ask what the thread is made of; nobody does.

Upkeep: Brush them off. Bring them in when the season turns.

Polypropylene

Hose it clean · never let it dry underneath the furniture

A flatweave polypropylene rug is the most forgiving thing on a patio: it takes rain, it takes a hose, and jewel tones hold their depth for years. The failure is not the rug, it is what happens beneath it. A rug left wet under a table traps moisture against stone or decking and leaves a ghost of itself in mildew. Lift it, let both sides dry, put it back.

Upkeep: Ten minutes after heavy rain. Lift it, do not just sweep it.
